CAR tech: who's to blame for your car's terrible fuel economy?

In early 2013 Audi lost a case brought by the Advertising Standard Agency (ASA) because of ‘misleading’ fuel economy figures used in an advert, after a customer complained they couldn’t get anywhere near the 68mpg quoted. The court case once more exposes the yawning gap between officially sanctioned mpg figures and those experienced by owners. A recent study by the Independent Council on Clean Transportation (ICCT) looked at cars sold in the UK and Europe, and discovered the difference between official mpg figures and real-world driving had grown from 8% in 2001 to a barely believable 21% in 2011.

Watch the Jaguar Project 7 F-Type go up the Goodwood hillcimb

Jaguar Project 7 F-Type (pictured) tackles the Goodwood FoS hillclimb One of the surprises of the 2013 Goodwood Festival of Speed has been the debut of the Jaguar Project 7 car, an F-Type with the more bountiful 542bhp supercharged V8 and styling stolen from the D-Type. Jaguar are saying Project 7 isn’t heading for production, but we’re pretty sure most of what’s underneath it – principally the 542bhp version of the supercahrged V8 – is in a production F-Type R. Perhaps surprisingly, fitting the 542bhp vresion of the V8 doesn’t seem to have done a lot for the F-Type’s sprint times, with 62mph coming up in 4.1 seconds, just 0.1 seconds quicker than the 495bhp engine in the standard Jaguar F-Type V8.

Jeep Grand Cherokee, there’s an app for that

Chrysler said on Thursday that it will release its owner’s manuals as smartphone apps. This is in addition to replacing its hard-copy owner’s manuals with DVDs and small quick-reference guides, something it did last year. The first iPhone manual will be available on June 19, for the 2011 Jeep Grand Cherokee.
